VULCANIZ ER.

SPECIFICATION forming part of Letters Patent No. 662.231, dated November 20, 1900.

Application filed April 13, 1900.

To all whom it may concern.-

Be it known that LPHILIPP FUNoK,of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Vulcanizers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specification, and

to the reference-numerals marked thereon.

Mypresent invention has for one object to provide a simple and improved closure for vulcanizers or similar vessels that is capable of being operated quickly by a single movement of a handle or operating part to close the receptacle and form atight joint between the retort and the cover therefor, and has for its further object to provide a means of support for the latter whereby it may be turned to one side to allow free access to the retort and also easily adjusted to take up wear between the parts.

To these and other ends my invention consis'ts in certain improvements in construction and combination of parts, all as will be described, and the novel features pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a vertical sectional view of a vulcanizer constructed in accordance with myinvention. Fig. 2 is a similar view taken on the line 2 2 of Fig. 1. Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 2. Fig. 4 is a similar'view on the line 4 4 of Fig. 2, and Fig. 5 is a side elevation of the cam-ring.

Similar reference-numerals in the several figures indicate similar parts.

1 indicates the base or support, preferably circular in form, upon which rests the retortframe 2, secured by screws 3 passing through the support and engaging lugs 4. on the lower side of the frame.

5 indicates a yoke-frame extending above the retort 6 and adapted to be turned to the side, having a shoulder 7 upon one end bearing upon a lug or projection 8 and a pin 9 extending vertically through the latter and provided with a nut 10, which secures the yoke on the frame. The opposite end of the yoke Serial No. 12,734:- (No model.)

the normal position to prevent its upward movement and hold it rigid upon the frame when pressure is applied to lock the cover on the retort. A handle 13 is applied to the free end of the yoke, forming a convenient means for operating it laterally. The cover or closure 14 is adapted to be held stationary relative to the retort 6, and the latter is adjusted 'vertically to close the parts, and in order that the said adjustment may be limited or any wear between the parts compensated forI attach the cover to the yoke by means of an adjustingscrew 16, having its lower end shouldered and bearing against the bottom of a central recess in the former. The cover is attached to the screw and permitted a free rotary movement thereon by means of a pin 17, passed through one side of the recess and engaging in an annular groove 18, formed near the end of the screw. A collar 19,having a milled edge,serves to adjust the screw to raise or lower the cover 14, and a set-screw 20 looks it in the desired position.

21 indicates a suitable packing ring arranged between the lower side of the cover and the upper edge of the retort, making a steam-tight joint.

The retort is arranged centrally within the casing, and beneath the cover and about its upper edge is a flange or ring forming a shoulder 22 upon the exterior of the retort and upon which the latter is supported on a vertically-movable ring 23, adjustably mounted in the frame 2, but prevented from rotary movement and removal therefrom by screws 24.

The vertical movement of the ring is accomplished by means of a revoluble collar 25, located below the latter, having the inclined or spiral way upon its lower side cooperating 0- with a similar surface 26, formed upon a stationary ring 27, held upon a step or rim 28, formed at the bottom of the frame, to which it is secured by a screw 29. Grooves 30 are formed in the upper and lower edges of the movable collar and in the proximate faces of the rings 23 and 27, and arranged therein are balls 31 to reduce the friction between the parts and permit their easy operation. The grooves formed in the cam-surfaces are not continuous owing to the difference in elevation between their opposite ends, and between these surfacesI arrange only a sufiicient number of balls in the grooves to permit their lineal movement as the collar is rotated, a screw or pin 32 being provided at the end of the groove to limit their upward movement, and a similar pin 33 at the opposite end arrests the downward travel. This arrangement allows the balls to roll along the grooves in the direction of the moving part, reducing the friction to a minimum. An operatinghandle 34, mounted upon a pin 35, operating through an aperture 36 in the frame and threaded into the collar, provides a simple means for operating the latter, and the length of the aperture can be arranged, if desired, to limit its movement.

A short pipe 40, communicating with the interior of the vessel, is provided in the cover 14, upon which may be mounted any suitable gage for registering the steam-pressure, and by mounting the cover upon theyoke and arranging the parts to move bodily out of line with the retort I obviate the inconvenience in handling the latter when the gage is connected directly thereto, and by so mounting it the parts are always in a convenient position for use and not liable to injury by unnecessary handling.

The operation of the device will now be readily understood. The collar 25 is revolved to its lowermost position on the spiral camway on the ring 27 and the retort 6 is suspended on the ring 23. The yoke 5 is now moved into position, with its hook 11 beneath the pin 12, and the cover is adjusted loosely above the retort by means of the screw 16, allowing the free lateral movement of the yoke, and the set-screw 2O prevents the accidental movement of the cover, and its subsequent adjustment is only necessary to take up the wear between the parts. The collar 25 is then revolved by means of the handle 34 in the direction indicated by the arrow in Fig. at, when the cooperating cam-surfaces will elevate the ring 23, carrying with itthe retort, the upper edge of which will engage the packing-ring 21, forming a tight joint between the parts.

Vulcanizers constructed according to my invention are simple and effective in their operation,and by arranging the balls between the bearing-surfaces and employing the long cam-surfaces the retort and closure therefor can be held tightly together and be very easily applied and adjusted.

I claim as my invention- 1. In a vulcanizer,tl1e combination with the retort having the flange, the frame surrounding the retort, having a cam-surface, and the cover connected to the frame and held stationary above the retort, of the clampingcollar extending loosely around the retort beneath the flange and capable of rotation independently thereof, and having a camsurface cooperating with the corresponding surface on the frame to move the retort and cover relatively.
